The lexan was backed by aluminum standoffs to prevent it from straightening out, and it worked perfectly.
Good luck!

We achieved a performance gain when we switched from traction backed to smooth.
I'm sure there are combinations of variables that cause a tractioned setup to work better, but or our specific setup smooth was better.
We tested this over a range of compression for both, so it wasn't just the compression difference. I think it's because our flywheel had very little inertia, and that "locking" into the disc with high traction probably dumped a lot of energy.
Shooters are black magic.
